An approach for synchronizing operation of a first communications terminal with operation of a second communications terminal involves establishing a communications link between the first communications terminal and the second communications terminal, the communications link being defined by a communication standard; and synchronizing a first clock coupled to the first communications terminal with a second clock coupled to the second communications terminal by receiving a time standard signal into the first communications terminal independently of the communication standard. This approach can be implemented using a first clock; a first communications terminal coupled to the first clock; a second clock; a second communications terminal coupled to the second clock; a communications link defined by a communication standard; and a transmitter transmitting a time standard signal independently of the communication standard to the first clock and setting the first clock in response to the time standard signal.

[ What is claimed is:] [1.]1. An apparatus comprising:a wireless receiver that is configured to receive a signal via a wireless connection;a time signal receiver that is configured to receive a time of day signal via a connection other than the wireless connection; anda controller that is configured to switch said wireless receiver to and from an active mode where said wireless receiver can receive the wireless connection signal and a sleep mode in which said wireless receiver cannot receive the wireless connection signal according to a schedule,wherein said controller determines the schedule in accordance with the time of day signal received by said time signal receiver via the connection other than the wireless connection, andwherein a sleep mode scheduled for said wireless receiver by said controller is overridden in response to turning on of said apparatus during the scheduled sleep mode, and is overridden in response to existence during the active mode of a wireless connection in progress to said wireless receiver.
